Galan Moody Associate Professor - Electrical and Computer EngineeringUniversiIty of California, Santa Barbara Abstract: Integrated photonics is revolutionizing how we generate, manipulate, and transmit quantum information. While the scalability and manufacturability of silicon-based photonics has been a driver of many quantum photonic technologies over the past two decades, future progress will require hybrid and heterogeneous integration strategies that can take advantage of different materials. In this presentation, I’ll focus on AlGaAs and InGaP, III-V semiconductor platforms that combine mature fabrication technology, a direct bandgap for electrical injection, low-loss operation, and large optical nonlinearities for efficient quantum light generation and conversion. After a brief background and introduction to progress in the field, I’ll discuss how III-V devices are made at wafer-scale, which we have utilized for high-rate entangled-photon pair generation and on-chip squeezing with performance that rivals bulk optics at a fraction of the size and power. I’ll highlight some emerging applications, including: (1) multi-node entanglement distribution over deployed fiber for networking, cryptography, and quantum time transfer, (2) development and integration of tunable chip-scale lasers for turnkey and compact quantum modules, and (3) methods for massive multiplexing using arrays of quantum frequency combs for reconfigurable quantum states. I’ll conclude with future challenges and exciting prospects in the next 5-10 years.

Bhavin Shastri Assistant Professor - Physics, Engineering Physics & Astronomy Centre for Nanophotonics Queens University Abstract: Artificial intelligence (AI) powered by neural networks has enabled applications in many fields (medicine, finance, autonomous vehicles). Digital implementations of neural networks are limited in speed and energy efficiency. Neuromorphic photonics aims to build processors that use light and photonic device physics to mimic neurons and synapses in the brain for distributed and parallel processing while offering sub-nanosecond latencies and extending the domain of AI and neuromorphic computing applications. We will discuss photonic neural networks enabled by CMOS-compatible silicon photonics. We will highlight applications that require low latency and high bandwidth, including wideband radio-frequency signal processing, fiber-optic communications, and nonlinear programming (solving optimization problems). We will briefly introduce a quantum photonic neural network that can learn to act as near-perfect components of quantum technologies and discuss the role of weak nonlinearities.

Jacob Bulmer Quantum architect - Psi Quantum Abstract: PsiQuantum is working to build a useful, fault tolerant quantum computer using photonics. This talk will discuss our progress towards this goal focusing on the hardware development including: integrated photonics components, demonstrations of high-fidelity quantum operations, and building large-scale cryogenic infrastructure. Biography: Dr Jacob Bulmer completed an MSci in Physics from Imperial College London in 2017 where he wrote his master’s thesis under the supervision of Prof Terry Rudolph and Dr Pete Shadbolt. After short periods at PsiQuantum and the University of Oxford he then completed his PhD at the University of Bristol in 2022. At Bristol, he worked in the Quantum Engineering Technology Labs under the supervision of Prof Anthony Laing on a range of theoretical, computational, and experimental projects in quantum photonics. Jacob now works at PsiQuantum in the Quantum System Architecture team, focusing on how best to leverage photonics hardware to realize scalable and performant quantum computing architectures. He is based in Bristol, UK.
